Aim:
The course provides basic knowledge about problems and methods
for construction of radio communication systems. The main
emphasis is on digital radio systems. In particular it is
illustrated how different forms of signal processing are used
for the construction of efficient radio communication systems.
After completed course the student should be able to
- perform link budget calculations in connection to the design of wireless communication links.
- identify and describe various physical and statistical fading channel models.
- present modulation techniques for wireless communication and their spectral properties as well as evaluate their performance over fading channels.
- give an account for coding techniques which can be used for improvement of the transmission reliability.
- describe and solve problems about direct sequence and frequency hopping band spreading techniques.
- analyse and describe properties for various diversity methods.
- give an account and solve problems about ARQ and some basic multiple access techniques.

Prerequisites: (valid for students admitted to programmes within which the course is offered)
Signal Theory and Telecommunications. Preferably also Digital Communications.
Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.

Organisation:
The course consists of lectures, exercise sessions and a
project work. The project is performed in groups of two
students. Each group chooses a topic from a list provided by
the lecturer. The group work starts with a search for suitable
information sources which have to be approved by the lecturer.
The work is expected to take approximately 5 weeks and results
in a written report. The course is concluded with two lectures
where the presence is compulsory on which the groups present
their projects. The lectures are given simultaneously with the
project work.

Course contents:
Lectures and exercise sessions treat the following areas within radio communications:
- Basics about radio communication systems: utilisation of the
frequency spectrum, different radio systems.
- System oriented antenna and wave propagation theory:
propagation in free space, in the troposphere, in the
ionosphere, basic antenna theory, link budget.
- Probabilistic channel models: fading channels,
time and frequency dispersive channels, digital channel
models.
- Modulation methods for the radio channel: bit error
analysis in fading channels, spectral properties, spectral
efficient modulation.
- Diversity methods: principles, weighting, performance.
- Coding for radio channels: methods for burst error correction, coding gain.
- Spread spectrum techniques: frequency hopping, direct
sequence systems.
- Multiple user systems: space- time-, frequency and
code multiplexing.
- Wireless packet transmission: ARQ, multiple access techniques.
- Multiple antenna systems and coding: MIMO, STBC.
- Practical examples: GSM, WLAN.
